We recently highlighted a video dispelling ten credit score myths in 60 seconds. Now the Wall Street Journal has chimed in with some other myths you should know, including why gunning for that oft-elusive perfect credit score is a waste of time.

According to the WSJ, a credit score of 800 or higher won't make you more attractive to lenders than a lower, though comparable credit score. Specifically, the paper says that while "every 20 points in your score can mean a slightly lower mortgage rate or better car loan," this is only true for scores up to the mid-700s. This means that if your score is in the 600s or low 700s, it's worthwhile to improve your numbers, but starting from the high 700s, spending your time striving for anything more is "meaningless."
